CABLE-POWER.

SPECIFICATION forming part of Letters Patent No. 681,632, dated August27, 1901.

Application filed July 16, 1900 To all whom it may concern:

Be it known that I, CLYDE J. EAsTMAN, a citizen of the United States,residing at Fort Worth, in the county of Tarrant and State of Texas,have invented certain new and useful Improvements in Cable-Power, ofwhich the following is a specilication.

This invention relates to cable-power obtained by means of movablewindlasses driven by steam or other motive power; and the object is toobtain a powerful draft for use in agricultural purposes, drawing heavyplows and reaping-machines, hauling heavy loads of ore or coal inmining, moving houses, and for drawing heavy loads of any description.

Other objects and advantages will be fully understood from the followingdescription and claims.

Reference is had to the accompanying drawings, which form a part of thisapplication.

Figure 1 is a plan view of the carriage and the driving mechanism. Fig.2 is a rear elevation of a trolley-yoke for automatically adjusting thecable. Fig. 3 is a plan view of the same, showing also means for takingup the slack of the stay-cable. Fig. 4 is a rear elevation of thecarriage, the cable being cut away. Fig. 5 is a detail view of africtionroller.

The means for producing the power are mounted on a carriage or platform1, and the platform is mounted on two pairs of wheels 2 and 3. Thewheels 2 turn on the axle 4. The steering of the carriage isaccomplished with these wheels. A shaft 5 is mounted in hangers 6, andchains 7 are attached to this shaft and to axle 4. A cog 8 is mounted onshaft 5, and a worm gear-wheel 9 is mounted on a hand-shaft 10, whichhas suitable bearings 11 and a hand-wheel12 for operating the shaft.When the carriage is moving, the direction can be changed by turning thewheel 12, and the direction to which the carriage will be turned dependson the turning of the hand-wheel. Turning in one direction will causethe carriage to change the direction and turning the hand-wheel in theopposite direction will start the carriage in the opposite direction.The chains 7 are wound oif and onto the shaft 5 and the axle 4 duringthe steering. The power is derived from the cable 13 and the windlasses14 and 15, with Serial No. 23,767. (No model.)

means for driving the windlasses. The windlasses are mounted in bearings1G. The power for driving the windlasses may be derived from anysuitable source. In the drawings a steam-engine 17 is shown inconventional form. This engine is provided with a balance-wheel 18 and ashaft 19. A cog-wheel 20 is mounted on the shaft 19 for driving acog-wheel 21, mounted on a shaft 22. Bevelpinions 23 and 24 are mountedon the shaft 22. These pinions drive the hevel-cogs 25 and 26, which aremounted rigidly on the shafts of the windlasses 15 and 14. Shaft 22 is`provided with suitable bearings 27. The cable 13 is wound around eachwindlass several times and in operation winds olf and on both windlassesat the same time. Two windlasses are used to prevent slipping of thecable on the windlasses. Means are provided for converting the carriageinto a traction-engine. This is necessary in order that the carriage canbe moved from place to place. A lever 28 is provided for throwing thecog 21 in and out of mesh with cog 20. A cog 29 is mounted on a shaft30, which is provided with bearings 31. Bevel-pinions 32 and 33 aremounted on shaft for driving a bevel-cog 34, which is mounted on shaft35. This shaft is provided with bearings 36. The bevel-cog has integraltherewith a cog-wheel 37 for driving a cog 33, mounted on axle 39 of thewheels 3. By these means power may be transmitted from the engine to thewheels 3. A lever 40 is provided for throwing the cog 29 in and out ofmesh with the cog 2O of the engine 17. By the mechanism thus describedit will be seen that the power of the engine can be exerted on thewheels of the carriage. The two pinions 32 and 33 are usedfor drivingthe carriage in different directions. For moving in one direction thepinion 32 is thrown in mesh with the bevel-cog 34, and for moving in theopposite direction pinion 35 is thrown in mesh with that cog. A lever 41is provided for throwing the pinion 35 in and out of mesh with the cog34, and a lever 42 is provided for throwing the pinion 32 in and out ofmesh with cog 34. In operation the cog 29 is to be out of mesh with thecog 2O of the engine; but when the carriage is to be moved the cog 21 isthrown out of mesh with the cog 2O and the cog 29 is to be thrown in IOOmesh with that cog 20. Brackets 43, provided with braces 44' forantifriction-rollers 44, arel windlass l5, and one may be mounted adja;

cent to the windlass 14. This roller is mounted in spring-pressedbearings 46. These bearings are mounted in casings 47. The bearings aremounted on springs 48, which are attached to blocks 48. Blocks 48 reston cams 49, which are mounted on a. shaft 50, and this shaft is providedwith a handle or lever 51. When the lever is moved, the cams will causethe roller 45 to press the cable 13 against the windlass. Means areprovided for automatically adjusting the cable 13. The cable is to beattached firmly at each end to stationary objects relative tolongitudinal movement. There must be no yielding of the object towardthe cable. In case this power is used for plowing, two posts 52 and 53are inserted in the ground at each end of the eld and the posts of eachend are to be about two hundred feet apart. A stay-cable 54 is attachedto each post and means are provided for taking up the slack of thestay-cables. A rod 55 is attached to one post, and a turnbuckle 56 isprovided with a ring 57, having a swivel connection with the turnbuckle.If the slack is very great, the stay-cable can be passed around the postanother time. The power-cable is attached to the stay-cable by means ofa trolley-yoke 5S. The trolley-yoke consists of a frame or base 59, atriangular frame GO, antifriction pulley-wheels 61, journaled in saidframe and base, and a ring 62 for securing the power-cable 13. This ring'is secured in the trolley-yoke by means of a bolt 63, passing throughthe base 59 and the frame 60. It will be understood that thetrolley-yoke can move on the stay-cables however much power may beexerted on the powerycable. Thus lateral adjustment is provided for theends of the power-cable, and this adjustment is perfectly automatic. Thepower is obtained through the cable by driving the vwindlasses with asuitable motive power. The object to be moved is to be attached to the`carriage in any suitable way. The power may be utilized to draw a dozenor more plows, or it may be used to move houses or other heavy objects.

The illustrations show the carriage provided with four wheels. It isobvious that any number of wheels maybe used. Even a less number ofwheels than the illustrations show can be used without departing fromthe invention. It is also obvious that one of the windlasses may bedispensed with and the invention will be the same in principle.Variousother changes may be made in the assembling of the various partswithout departing from the spirit of the invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-
